improvements in Vlfindow Construction, of

which the following is a specification.A

This invention relates to improvements in window construction and one ofthe objects of the saine is to improve and simplify the construction ofwindows and the manipulation of the sashes, so that the lower sash maybe raised to a position adjacent to the upper sash and both sashes swungopen to insure a larger quantity of' fresh air, particularly in asleeping room, in lieu of sleeping porches.

A further object is to provide an irnproved structure of this characterwhich may be readily adapted for use in all houses.

Other and further objects will appear from the following specificationand claim when taken in connection with the accompanying drawing, and inwhich;

Figure 1 is a vertical longitudinal view in section, of an improvedwindow of this character vconstructed in accordance with the principlesof this invention, and showing in dotted lines the parts in differentpositions. Fig. 2 is a front elevation of the window and with both ofthe sashes closed. Fig. 3 is an enlarged detail view showing the recessin the frame for receiving the projecting members on the lower sashvwhen the latter is swung open.

ln the drawing the window frame is provided with the vertical side walls10, 10, and the sill 11, each of the sidewalls being provided in itsupper portion with a longitudinal groove 12, and a. parting strip 13 isarranged in the lower portion of the frame below the groove 12.

An upper sash 141, is arranged in the frame and is secured in positionby hinges 15, secured to the top of the sash and to the frame so thatthe sash will swing about a horizontal pivot, and so that the bottom ofthe sash will proj ect laterally beyond the frame. The ordinary and wellknown construction of spring catches 16, are connected with the sash andare adapted to enter openings 17, in the frame to secure the sashagainst swinging movement.

rlhe upper edges 18, of' the parting strips 13, terminate some distanceshort of the lower edge 19, of the upper sash, fora purpose to behereinafter set forth.

To the top of the lower sash 20, are se cured members 21, which projectfrom opposite sides thereof and enter the grooves 12, inthe verticalwalls of the frame and are adapted to move in the grooves when the lowersash is raised and lowered, and the lower sash is held againstadjustment by spring catches 22, similar to the catches 16, and whichenter openings 23 in the frame.

A recess 24 is provided in each of the side walls of the frame and theserecesses open into the grooves 12, in the respective side walls, and areadapted to receive the members 21, on the lower sash when the latter israised and swung laterally. These recesses 211 are preferably arrangedadjacent to the hinges or pivots of the upper sash adjacent to the topof' the frame. A

llVhen the sashes areclosed, the lower edge of the lower sash standsinside of the sill 11, and when it is desired to open the window, thecatches of the lower sash are first released and the lower sash raised afew inches until the lower edge thereof clears the win-r dow sill 11,and can then be swung later ally, preferably into the room. IThe lowersash may then be lowered until the members 21, thereon abut and restagainst the upper ends of' the parting strips 13. rihis position of thelower sash will leave a space between the top thereof and the lower edgeof the upper sash. rThe catches 16 on the upper sash are then releasedand that sash may be thenswung laterally on its pivot or hinges 15, andmay be maintained in its open position by means of the catches 16,engaging in openings in the end 2dr of a support 25, which is pivotallyconnected as at 2G, with the window frame, and which support when not inuse, hangs against the frame. rlhe lower sash may then be raised causingthe members 21, to slide in the grooves 12, until they stand oppositethe recesses 24C. rlhe members may then be moved back into the recessesand the lower edge of the sash moved to swing the lower sash laterallyon the pivot formed by the members and the recesses. This will cause thelower sash to stand close to, and substantially parallel with the uppersash and may be maintained in this position by means of the catches 22,detachably engaging a branch 27, connected with the support 25,preferably by a pivot 28, so that the branch 27, may fold with respeotto the support 25, when not in use.

What is olaimed as new is;

A window embodying a frame having its vertical side walls provided witha longitudinaly groove therein, a sash pivotally mounted in the upperportion of the frame, a lower sash, means connected with the lower sashand movable in the said grooves, the saidl means cooperating with thegrooves to form a pivot about which the lower sash swings when thelatter is moved above the sill, a stop Cooperating with the said meansCopies of this patent may be obtained for ve cents each, by addressingthe Commissioner f Patents,

to limit the lowering movement. ofthe sash, asupport cooperating withthe frame and the upper sash for holding the latter in an open position,and means for holding the lower sash in open position and in closeproximity to the upper sash.

In witness whereof, I hereunto subscribe my name to this specificationin the presence of two witnesses.
